Pass

– Click it to have an inquiry for data transmission

between the hosts located on both sides of VPN Tunnel while

connecting.

Block

– When there is conflict occurred between the hosts on

both sides of VPN Tunnel in connecting, such function can

block data transmission of Netbios Naming Packet inside the

tunnel.

Multicast via VPN

Some programs might send multicast packets via VPN

connection.

Pass

– Click this button to let multicast packets pass through

the router.

Block

– This is default setting. Click this button to let

multicast packets be blocked by the router.

User Name

This field is applicable when you select PPTP or L2TP with or

without IPSec policy above.

Password

This field is applicable when you select PPTP or L2TP with or

without IPSec policy above.

IKE Authentication

Method

This group of fields is applicable for IPSec Tunnels and L2TP

with IPSec Policy when you specify the IP address of the

remote node. The only exception is Digital Signature (X.509)

can be set when you select IPSec tunnel either with or without

specify the IP address of the remote node.

Pre-Shared Key -

Check the box of Pre-Shared Key to invoke

this function and type in the required characters (1-63) as the

pre-shared key.

Digital Signature (X.509) –

Check the box of Digital

Signature to invoke this function and Select one predefined

Profiles set in the

VPN and

Remote Access >>IPSec Peer

Identity.

IPSec Security Method

This group of fields is a must for IPSec Tunnels and L2TP

with IPSec Policy when you specify the remote node. Check

the Medium, DES, 3DES or AES box as the security method.

Medium-Authentication Header (AH)

means data will be

authenticated, but not be encrypted. By default, this option is

invoked. You can uncheck it to disable it.

High-Encapsulating Security Payload (ESP)

means payload

(data) will be encrypted and authenticated. You may select

encryption algorithm from Data Encryption Standard (DES),

Triple DES (3DES), and AES.

Local ID -

Specify a local ID to be used for Dial-in setting in

the LAN-to-LAN Profile setup. This item is optional and can

be used only in IKE aggressive mode.

4.9.6 LAN to LAN

Here you can manage LAN-to-LAN connections by maintaining a table of connection

profiles. You may set parameters including specified connection direction (dial-in or

dial-out), connection peer ID, connection type (VPN connection - including PPTP, IPSec

Tunnel, and L2TP by itself or over IPSec) and corresponding security methods, etc.

The router supports 2 VPN tunnels and provides up to

32

profiles simultaneously. The

following figure shows the summary table.

Set to Factory Default

Click to clear all indexes.

Name

Indicate the name of the LAN-to-LAN profile. The

symbol

???

represents that the profile is empty.

Status

Indicate the status of individual profiles. The symbol

V and X represent the profile to be active and

inactive, respectively.

Click each index to edit each profile and you will get the following page. Each LAN-to-LAN

profile includes 4 subgroups. If the fields gray out, it means you may leave it untouched. The

following explanations will guide you to fill all the necessary fields.

For the web page is too long, we divide the page into several sections for explanation.

Profile Name

Specify a name for the profile of the LAN-to-LAN connection.

Enable this profile

Check here to activate this profile.

Netbios Naming Packet

Pass

– When there is conflict occurred between the hosts on

both sides of VPN Tunnel in connecting, such function can

block data transmission of Netbios Naming Packet inside the

tunnel.

connection.

– Click this button to let multicast packets pass through

the router.

– This is default setting. Click this button to let multicast

packets be blocked by the router.

Always On or Idle

Timeout

Always On-

Check to enable router always keep VPN

connection.

Idle Timeout:

The default value is 300 seconds. If the

connection has been idled over the value, the router will drop

the connection.

Enable PING to keep

alive

This function is to help the router to determine the status of

IPSec VPN connection, especially useful in the case of

abnormal VPN IPSec tunnel disruption. For details, please

refer to the note below. Check to enable the transmission of

PING packets to a specified IP address.

PING to the IP

Enter the IP address of the remote host that located at the

other-end of the VPN tunnel.

Enable PING to keep alive

is used to handle abnormal IPSec

VPN connection disruption. It will help to provide the state of a

VPN connection for router’s judgment of redial. Normally, if

any one of VPN peers wants to disconnect the connection, it

should follow a serial of packet exchange procedure to inform

each other. However, if the remote peer disconnect without

notice, Vigor router will by no where to know this situation. To

resolve this dilemma, by continuously sending PING packets to

the remote host, the Vigor router can know the true existence

of this VPN connection and react accordingly. This is

independent of DPD (dead peer detection).

Type of Server I am

calling

PPTP

- Build a PPTP VPN connection to the server through

the Internet. You should set the identity like User Name and

Password below for the authentication of remote server.

IPSec Tunnel

- Build an IPSec VPN connection to the server

through Internet.

L2TP with IPSec Policy -

Build a L2TP VPN connection

through the Internet. You can select to use L2TP alone or with

IPSec. Select from below:

None:

Do not apply the IPSec policy. Accordingly, the VPN

connection employed the L2TP without IPSec policy can be

viewed as one pure L2TP connection.

Nice to Have:

Apply the IPSec policy first, if it is applicable

during negotiation. Otherwise, the dial-out VPN connection

becomes one pure L2TP connection.

Must:

Specify the IPSec policy to be definitely applied on the

L2TP connection.

User Name

This field is applicable when you select, PPTP or L2TP with or

without IPSec policy above.

Password

This field is applicable when you select PPTP or L2TP with or

without IPSec policy above.

PPP Authentication

This field is applicable when you select, PPTP or L2TP with or

without IPSec policy above. PAP/CHAP is the most common

selection due to wild compatibility.

VJ compression

This field is applicable when you select PPTP or L2TP with or

without IPSec policy above. VJ Compression is used for

TCP/IP protocol header compression. Normally set to

Yes

to

improve bandwidth utilization.

IKE Authentication

Method

This group of fields is applicable for IPSec Tunnels and L2TP

with IPSec Policy.

Pre-Shared Key

- Input 1-63 characters as pre-shared key.

Digital Signature (X.509)

- Select one predefined Profiles set

in the

VPN and Remote Access >>IPSec Peer Identity

.

IPSec Security Method

This group of fields is a must for IPSec Tunnels and L2TP with

IPSec Policy.

Medium AH (Authentication Header)

means data will be

authenticated, but not be encrypted. By default, this option is

active.

High (ESP-Encapsulating Security Payload)-

means payload

(data) will be encrypted and authenticated. Select from below:

DES without Authentication

-Use DES encryption algorithm

and not apply any authentication scheme.

DES with Authentication-

Use DES encryption algorithm and

apply MD5 or SHA-1 authentication algorithm.

3DES without Authentication

-Use triple DES encryption

algorithm and not apply any authentication scheme.

3DES with Authentication-

Use triple DES encryption

algorithm and apply MD5 or SHA-1 authentication algorithm.

AES without Authentication

-Use AES encryption algorithm

and not apply any authentication scheme.

AES with Authentication-

Use AES encryption algorithm and

apply MD5 or SHA-1 authentication algorithm.

Advanced

Specify mode, proposal and key life of each IKE phase,

Gateway, etc.

The window of advance setup is shown as below:

IKE phase 1 mode -

Select from

Main

mode and

Aggressive

mode. The ultimate outcome is to exchange security proposals

to create a protected secure channel.

Main

mode is more secure

than

Aggressive

mode since more exchanges are done in a

secure channel to set up the IPSec session. However, the

Aggressive

mode is faster. The default value in Vigor router is

Main mode.

IKE phase 1 proposal-

To propose the local available

authentication schemes and encryption algorithms to the VPN

peers, and get its feedback to find a match. Two combinations
